A versatile alpine pack developed with pro alpinists Stephan Siegrist and Nico Hojac for climbing, ski touring, and mountaineering. The Trion 28 Women's serves up lightweight comfort at just 990g with exceptional durability through robust, abrasion-proof outer material and a water-repellent PFC-free DWR finish. Made primarily from recycled materials with Bluesign Product and Fair Wear certifications. The women's specific design features a tailored back length, hip belt, and shoulder straps for a natural, comfortable carry, while the contact back system ensures optimal load transfer. A rolltop closure with zipper provides flexible packing, and zippered side access to the main compartment lets you reach your gear without unpacking. Two ice axe attachments, reinforced side ski attachment, trekking pole carrier, and a rope attachment on the flap handle all your technical gear. Hydration system compatible.
